linux kernel logs

Hi,

I tried yesterday linux kernel 4.14.25 but it crashed after starting kde
plasma 5.12.3 with pulseaudio 11.1. After the crash I could ping but
couldn't access over ssh. I need to do hard reset, but fortunately I
have logs that I leave in attachment.

I'm using kernel 4.9.86 without any problem and gentoo distro with
profile 17.0.

I have already contact kernel-janitors mailing list asking for what dev team should I report this bug.

as the kernel dmesg says
Mar 11 02:01:53 x99 kernel: snd_hda_intel 0000:02:00.1: Consider building the kernel with CONFIG_SND_DYNAMIC_MINORS=y
Mar 11 02:01:53 x99 kernel: snd_hda_intel 0000:02:00.1: Too many HDMI devices

Build the kernel with CONFIG_SND_DYNAMIC_MINORS=y and see if you still have problems

Thanks Alice. I'll test adding that configuration. I miss that log entry when I review the logs.

Btw, in kernel 4.9 that configuration wasn't necessary, since I've not any error registered so far.

I'll leave additional feedback after testing it.

After compiling the kernel with suggested configuration it worked without any error in logs.

cool thanks for checking
